1. Activity: Glove Selection

2. Activity: Glove Selection • In your groups discuss which PPE is/are required for the given scenarios below • PPE available in the lab are provided in the packet • Scenario 1: • You need to clean multiple pieces of glassware in a bucket containing 10% nitric acid. • Scenario 2: • You will need concentrated sulfuric acid to titrate a basic solution to neutral a pH of 7. • Scenario 3: • You need to prepare a 65:45 Acetonitrile/Methanol solution for you HPLC separation. • Scenario 4: • You need to dissolve your analyte into 100mL of Hexane. Take about 15 minutes to do this

3. Activity: Answers and Discussion • Were there any assumption you had to make? • Answers and Discussion • Scenario 1- Cleaning glassware in a 10% nitric acid bath • Latex, Vinyl, SOV-VEX, Neoprene, Silvershield • Scenario 2 - Pouring concentrated sulfuric acid into a beaker • Vinyl, Butyl, Silvershield • Scenario 3 - Creating a 65:45 Acetonitrile/Methanol solution • Latex, Vinyl, SOV-VEX, Neoprene, Butyl, Silvershield • Scenario 4 - Pouring 100mL of Hexane into a flask • Nitrile, SOV-VEX, Silvershield
